NOTE:  An OpenVMS saveset or PCSI installation file is stored
       on the Internet in a self-expanding compressed file.
       The name of the compressed file will be kit_name-dcx_vaxexe
       for OpenVMS VAX or kit_name-dcx_axpexe for OpenVMS Alpha.
 
       Once the file is copied to your system, it can be expanded
       by typing RUN compressed_file.  The resultant file will
       be the OpenVMS saveset or PCSI installation file which
       can be used to install the ECO.

ECO KIT SUMMARY:

An ECO kit exists for RMS and CONVERT on OpenVMS Alpha V7.0  This             
kit addresses the following problems:      


PROBLEMS ADDRESSED IN ALPRMS02_070 KIT:

  o  Fix for NULL KEY option for PACKED DECIMAL key type.                 
                                                                              
     This problem is restricted  to  an  indexed  file  that  has  a      
     secondary  key  type  of PACKED DECIMAL and the NULL KEY option          
     set.  In performing adds or updates to the  indexed  file,  the          
     application may ACCVIO.  The process may either:                         
                                                                              
                                                                          
      o  Terminate (SYSGEN parameter BUGCHECKFATAL not enabled) with      
         an access violation (ACCVIO); or                                     
                                                                              
      o  Crash the system (BUGCHECKFATAL enabled) with a  SSRVEXCEPT      
         (unexpected system service exception) ACCVIO error.                  
                                                                              
                                                                          
     NOTE:  Until this remedial kit can be installed,  this  problem      
     can be prevented from reoccurring by converting the file with a          
     revised FDL in which the null key option for the packed decimal          
     secondary key has been changed to "no."                                  

  o  Fix for explicit $extend to a relative file.                         
                                                                              
     The last data record(s) added at the end of a relative file may      
     be  lost  (overwritten)  after  an  "explicit"  call to the RMS          
     $EXTEND service for a relative file that is being shared by two          
     or  more  concurrent writers.  This problem is restricted to an          
     explicit $EXTEND; autoextends done transparently by RMS  for  a          
     relative file work correctly.                                            
                                                                              
     NOTE:  Until this remedial kit can be installed,  this  problem      
     can be prevented by not doing any explicit $EXTEND for a shared          
     write relative file.  Let the autoextend feature  of  RMS  take          
     care  of  any  extends needed.  See "Relative File Extend Size"          
     section in chapter 3 (Performance Considerations) of the  Guide          
     to  OpenVMS  File  Applications  for  a  description of how RMS          
     derives the value it uses for its autoextend feature.                    
                                                                              
  o  Fix for exec-mode access violation (ACCVIO) that  results  from      
     issuing  an  RFA  access  using  a VBN that exceeds the highest          
     block (out-of-range) currently allocated to a file.                      
                                                                              
     The ACCVIO will only occur if the out-of-range  RFA  access  is      
     done  to  a  file  that  is both an indexed file and has global          
     buffers enabled.  If the SYSGEN parameter BUGCHECKFATAL is  not          
     enabled, then the process will be terminated; if it is enabled,          
     then the system will crash with a SSRVEXCEPT ACCVIO.                     
                                                                              
     Note:  RFA access is a rare access mode for an  application  to      
     use  with  an  indexed  file;  an out-of-range RFA access to an          
     indexed file should be even rarer.                                       
                                                                              
  o  Fix for appender lock timing window hang for shared  write,  RU      
     journaled sequential file.                                               
                                                                              
     This hang requires all of the following conditions:   a  shared      
     write  sequential  file,  multi  record  streaming  enabled, RU          
     journaling enabled on the  file,  and  heavy  write  contention          
     among sharers at the end-of-file.  It has only been reported by          
     one site, and even then there was a  lapse  of  over  one  year          
     between two occurrences.                                                 
                                                                              
  o  Fix for inconsistent  secondary  key  in  RU-journaled  indexed      
     file.                                                                    
                                                                              
     It is possible for an indexed file with more than one secondary      
     key allowing no duplicates to show an inconsistent total number          
     of data records as being accessible via  two  or  more  of  the          
     secondary  keys.   In order for this problem to occur, the file          
     must have RU journaling enabled; as part of an RU  transaction,          
     a  secondary  data  record  must  be  deleted  in  one  of  the          
     nonduplicate secondary keys (will  be  marked  RU-DELETED)  and          
     then  an  attempt  must be made to add a duplicate key value to          
     another nonduplicate secondary key as part of a $PUT operation,          
     which results in a duplicate (DUP) error.                                
                                                                              
     As part of  the  recovery  triggered  by  the  DUP  error,  the      
     secondary key value marked as RU-DELETED will not be recovered.          
     This will leave the file with an  inconsistent  secondary  key.          
     However,  the  primary key contents will be intact and correct,          
     and a convert of the file will rebuild  the  secondary  indexes          
     and leave the file in a consistent state.                                
                                                                              
  o  XABITM stored semantics  attribute  fix  for  SMFS  (Sequential      
     Media File System) device.                                               
                                                                              
     Stored semantics is a file attribute used to  indicate  that  a      
     file  contains  compound  documents (i.e., contains a number of          
     integrated components including  text,  graphics,  and  scanned          
     images).   Support  for setting this file attribute is provided          
     through RMS using an item list XAB (XABITM) user interface.              
                                                                              
     In  specifying  the  item  list  for  setting  this   attribute      
     (XAB$_STORED_SEMANTICS),  a  user  may  request a return length          
     (the length of the stored  semantics  ACE  added  by  the  file          
     system  to  the file).  RMS without the fix returns a length of          
     zero if the file is on a SMFS device despite the fact that  the          
     stored semantics attribute was successfully added to the file.           
                                                                              
  o  %CONV-F-READERR converting undefined file format to fixed.           
                                                                              
     Converting a sequential file with an UNDEFINED record format to      
     a FIXED record format aborts with following errors:                      
       %CONV-F-READERR, error reading                         
       -RMS-F-UBF, invalid user buffer                                        
                                                                              
  o  Fix for EXCHANGE/NETWORK user-mode access violation (ACCVIO).        
                                                                              
     This  problem  only  occurs  when  the  convert   transfer_mode      
     (/TRANSFER_MODE=CONVERT)  option  is  used  with  a  file  that          
     exceeds 255 blocks in size.                                              
                                                                          
                                                                          
PROBLEMS ADDRESSED IN ALPRMS01_070 KIT:

                                                                          
  o  Make last chance handler more robust when process that has file      
     opened  with global buffers enabled is terminated with STOP/ID.          
     STOP/ID   invokes   the   RMS   abort   last   chance   handler          
     (RM$LAST_CHANCE).  Problems addressed include:                           
                                                                              
                                                                          
      o  A potential deadlock in the RMS last-chance handler if  the      
         same  file  is  open  more  than  once  within a process or          
         subprocess and it has global buffers set on it.                      
                                                                              
      o  A potential fatal KRNLSTAKNV system crash due  to  nonfatal      
         RMS  bugchecks from failing $GETLKI calls which cause error          
         rundown recursion until the stack fills up.                          
                                                                              
                                                                          
     These problems are fixed in the OpenVMS Alpha V7.1.                  
                                                                              
  o  Fix to exclude block I/O access from XAB area maximum check  on      
     the open of an indexed file.                                             
                                                                              
     This problem is fixed in OpenVMS Alpha V7.1.                         
                                                                              
  o  Fix for compressed primary  key  problem  that  occurs  in  the      
     context  of  record  deletes being done using sequential access          
     rather than keyed access.                                                
                                                                              
     Sequentially walking through (getting) the primary data records      
     in  an  indexed  file  (primary  key  is  a string key with key          
     compression enabled), a delete is done of one of  the  records.          
     The  following error may be returned when an attempt is made to          
     sequentially  get  the  next  record:   RMS-F-BUG,  fatal   RMS          
     condition, process deleted.                                              
                                                                              
     The file is not left corrupted.  A convert  of  the  file  will      
     leave the file in a consistent state.                                    
                                                                              
     This problem is fixed in OpenVMS Alpha V7.1.                         
                                                                              
  o  Fix for crash with kernel-mode caller.                               
                                                                              
     A kernel-mode caller may crash with  KRNLSTAKNV  (kernel  stack      
     not  valid).   A  page  in  the  kernel stack has the 'fault on          
     write' bit set.                                                          
                                                                              
     This problem is fixed in OpenVMS Alpha V7.1.                         
                                                                              
  o  Fix  for  RMS  bugcheck  NOTLOCKED  (R2=FFFFFFEF)   on   shared      
     sequential file.                                                         
                                                                              
     Process is delivered blocking AST to release file lock.  Before      
     releasing  file  lock,  it  has to release lock it holds on EOF          
     buffer.  NOTLOCKED bugcheck is returned if process  is  holding          
     PW  (protected  write)  rather  than EX (exclusive) lock on EOF          
     buffer.  The check should have been for either EX  or  PW  lock          
     (oversight in new routine added in OpenVMS Alpha V6.1).                  
                                                                              
     This problem is fixed in OpenVMS Alpha V7.1.                         
                                                                              
  o  Fix for loop when deleting network logical links.  Loop  occurs      
     at  exec-mode AST level and process cannot be deleted.  Process          
     in loop will be an application that does network operations.             
                                                                              
     RMS maintains a process cache of recent  logical  links  for  a      
     period  of  time  in an attempt to reuse them and save on image          
     and process activations.  When a link becomes inactive  and  is          
     added  to the cache, RMS deletes any links in surplus of three.          
     In walking the link cache queue to delete these links, there is          
     a potential race condition that could result in a stale pointer          
     being used after a stall, which leads to the loop.                       
                                                                              
     This problem is fixed in OpenVMS Alpha V7.1.                         
                                                                              
  o  Autoextend fix for shared block I/O write which requires use of      
     UPI option -- which disables any locking (file or EOF bucket).           
                                                                              
     For this particular case with no locking synchronization, it is      
     possible  if  two or more processes or two or more asynchronous          
     streams are writing to a file, that two or more autoextends may          
     occur concurrently.  Though the file system will do the extends          
     synchronously, the processing of the extend result may complete          
     out  of  sequence  and  result  in  RMS bugcheck FTL$_BADEBKHBK          
     (R2=FFFFFFDC).                                                           
                                                                              
     This problem is fixed in OpenVMS Alpha V7.1.                         
                                                                              
  o  Improved error reporting on ASB allocation failure.   If  there      
     is  a user context to return the error to, RMS$_DME will now be          
     returned instead of RMS$_BUSY.                                           
                                                                              
     When RMS allocates an Asynchronous Status Block  (ASB)  for  an      
     RMS  thread  from  process-permanent  pages (PIOPAGES), and the          
     allocation attempt fails due to lack of memory,  the  error  is          
     not  properly  handled:   in  some  cases the error is ignored,          
     leading to subsequent hangs and inconsistencies,  or  else  the          
     true cause of the error is obscured by overlapping bugchecks.            
                                                                              
     These allocation failures are most  likely  to  be  encountered      
     with  RMS  journaling  applications,  and  can  be  avoided  by          
     increasing the PIOPAGES SYSGEN parameter.                                
                                                                              
     This problem is fixed in OpenVMS Alpha V7.1.                         
                                                                              
  o  Fix for an indexed file with a fixed maximum record  size  less      
     than  4  bytes.   A  data record header (internal structure RMS          
     maintains in  the  on-disk  indexed  data  bucket)  may  become          
     corrupted  when  it is moved down in a data bucket to make room          
     for a new record.                                                        
                                                                              
     This problem is fixed in OpenVMS Alpha V7.1.                         
                                                                              
  o  Fix for SS$_ILLIOFUNC on some drivers.  This  can  happen,  for      
     example,  if  SYS$SCRATCH is defined to point to an MSCP-served          
     disk and MAIL attempts to  print  a  mail  message  to  an  RMS          
     temporary file.                                                          
                                                                              
     This problem is fixed in OpenVMS Alpha V7.1.                         
                                                                              
  o  Fix for SDA-W-FAOERR when displaying RMS FWA (File Work  Area).      
     The contents of a buffer (LOGNAM) are being displayed after the          
     space have been returned and reallocated for some other use.             
                                                                              
     This problem is fixed in OpenVMS Alpha V7.1.                         
                                                                              
  o  Statistics setting on a file is lost from the FDL  produced  by      
     ANALYZE/RMS/FDL.  File monitoring is always set to 'no' whether          
     it is enabled or not.  The problem is not  with  ANALYZE[/RMS],          
     but with RMS's processing of an XABITM list.                             
                                                                              
     This problem is fixed in OpenVMS Alpha V7.1.                         
                                                                              
  o  Fix  to  avoid  LIB-F-BADBLOADR  (bad  block  address)   errors      
     returned to CONVERT utility from SORT utility.                           
                                                                              
     The new high-performance  SORT/MERGE  utility  (HYPERSORT)  was      
     introduced in Alpha V7.0.  Currently HYPERSORT does not support          
     indexed file organizations.   To  avoid  a  number  of  convert          
     failures  that would occur if a process or system had redefined          
     SORTSHR to point to HYPERSORT, CONVERT, as of Alpha V7.0, links          
     to the SORT/MERGE object library.                                        
                                                                              
     A linkage modification to the SORT/MERGE  utility  changed  the      
     order  in  which  some PSECTs are collected in Alpha V7.0.  The          
     effect of this is that some sort cleanup routines  may  not  be          
     called  and  some  exit handlers not canceled, which results in          
     some rundown problems  for  images  (like  CONVERT)  that  call          
     SORT/MERGE routines.                                                     
                                                                              
     The following errors may be reported at the end of  a  convert,      
     after the convert has successfully completed and the new output          
     file has been closed:                                                    
                                                                              
         %SORT-E-SYSERROR, system service error                           
         -LIB-F-BADBLOADR, bad block address                                  
                                                                              
     In addition to the LIB-F-BADLOADR error (or errors), there  may      
     be an access violation reported:                                         
                                                                              
         %SYSTEM-F-ACCVIO, access violation, reason mask=00,...           
                                                                              
     Another side-effect of this SORT/MERGE utility  problem  for  a      
     convert of an indexed file that is sufficiently large enough to          
     require temporary  workfiles  for  the  sort  is  that  several          
     temporary  sortwork  files  in SYS$SCRATCH will survive (not be          
     deleted by sort).   The  default  names  of  these  files  are:          
     SORTWORK0.TMP and SORTWORK1.TMP.                                         
                                                                              
     This problem is fixed in OpenVMS Alpha V7.1.                         
                                                                              
  o  Non-indexed file opened with an indexed file  XAB  may  ACCVIO.      
     If  a  non-indexed file (sequential or relative) is opened with          
     one or more XABs specific to indexed files (XABKEY, XABSUM,  or          
     XABALL) chained to the FAB, the process may either:                      
                                                                              
      o  Terminate (SYSGEN parameter BUGCHECKFATAL not enabled) with      
         an access violation (ACCVIO); or                                     
                                                                              
      o  Crash the system (BUGCHECKFATAL enabled) with a  SSRVEXCEPT      
         ACCVIO.                                                              
                                                                              
     A necessary condition for this to occur  is  that  the  virtual      
     address  space  used  for  the program region (P0) must be more          
     than half a gigabyte.  In other words, it requires both a  very          
     large  application and one that has indexed XABs chained to the          
     FAB  for  a  non-indexed  file.   We  are  aware  of  only  one          
     application  that  this  problem  has  occurred  with  to date:          
     ALL-IN-1.                                                                
                                                                              
     This problem is fixed in OpenVMS Alpha V7.1.                         
                                                                              
  o  A put to an indexed file may ACCVIO.  The process may either:        
                                                                              
      o  Terminate (SYSGEN parameter BUGCHECKFATAL not enabled) with      
         an access violation (ACCVIO); or                                     
                                                                              
      o  Crash the system (BUGCHECKFATAL enabled) with a  SSRVEXCEPT      
         ACCVIO.                                                              
                                                                              
     Some Bliss-32 modules were converted to Bliss-64 as part of the      
     64-bit  project  for  OpenVMS Alpha V7.0.  A LDQ (load quad) or          
     MOVQ (move quad) instruction generated by the Bliss-64 compiler          
     may  result  in  an attempt being made to read or write 4 bytes          
     beyond the end of an RMS internal  buffer  to  an  inaccessible          
     page.                                                                    
                                                                              
     This problem is fixed in OpenVMS Alpha V7.1.
